SenCha Touch中Ext.create()和Ext.define()有什么区别 [英] What are differences between Ext.create() and Ext.define() in SenCha Touch

问题描述

我学习SenCha Touch已有一段时间了，但在尝试创建商店时仍然感到困惑.

I have been learning SenCha Touch for awhile and still feel confused when trying to create a store.

在SenCha文档中，它说使用Ext.create()示例 我尝试过，但是根本行不通.

In the SenCha Documentation, it says to use Ext.create() Example I tried and it simply doesn't work.

对于其他人，我总是看到人们使用Ext.define()创建商店，并且可以正常工作.

For the rest of others, I always see people use Ext.define() to create a store and it works.

现在，我的问题是: 它们之间有什么区别?何时/如何正确使用它们中的任何一个?

Now, my question is: what are the differences between them and when/how to use either one of them in a right way?

一些演示代码受到高度赞赏

Some demo code is highly appreciated

非常感谢我的朋友们.

推荐答案

define用于声明一个类.

Ext.define('Foo', {
    extend: 'Bar'
});

// Similar to:
public class Foo : Bar {
}

create用于创建实例:

var o = Ext.create('Foo'); // Can also have var o = new Foo();

// Similar to:
Foo o = new Foo();
